UNITED STATES GHABLESl-I. VON GLAHN, OF BROOKLYN, LNEVI YORK.

CHEESE SLICER.

t Original N0.v1,611,965, dated This application a continuationin part oi" my 'copending application, Serial No. 68,642, filed November 12,1925, for cheese Slicers.

The invention relates to Slicers for brick cheese, butter',yic`e cream, soa and similar "plastic or semi-plastic materia s, and has for an `object `to provide an improved ap aratus whereby material mayjbe cut into`\s 'ces of predetermined thickness.`

A further object of the invention is to provide an apparatus operable by one hand, in

which the material is automatically advancedwhile'the cutting element is being moved;

The invention consists in the novel construction hereinafter described, and illustrated in the accompanying drawings, in which: l f t Fig. 1 isa .front elevation of an apparatus embodying the invention; Y t

Fig. 2 is a side view of the same; Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2;

Fig. 4 is a rdetail view taken on theline` 4 4 of Fig. 1; y y

Fig. 5 is a detail view taken on theline 5 5 of Figrl. e

ln the drawings, the slicer comprises a base consisting of a iioor 1 havin an `integral guide wall 14 at one side an short distance above the counter or other sur face by integral legs 2, 3,4, and 5. The for wardlegs 2v and 3 areof substantial dimen-y sions, as shown, and provided Withy threaded bores in which lare mounted vertical posts 6 and 7 on which a cutter is mounted for vertical reciprocation. The cutter consists' of an inclined cutting wire 11 anda frame comrisin a handle 8 andftwo sleeves 9 and 10 iorme integraltherewith and adapted to receive posts 6 and 7 in sliding relatlon. Cut

ting wire 1-1 extends between the sleeves, be-

ng secured to sleeve 10 by a4 pin 12y and to I turning the key 50, and that they wire 11 is sleeve 9 by a tighteningkey as will be more fully described. Sleeve 9 has a depending flange 13 through which the wire 11 passes.`

Ay feeding n and is carried y an arcuate arm 16 having an end 17 Aadapted to slidefon a rod 18 journaledinvlateral studs 19' by means of straps 20. `Rod 18 is providedwith a spiral groove forming a left-hand thread, andv has a hand `wheel 21 keyed to its lrear end. A clutch* member 22 passes through the end 17 of arm `16 andv engages the spiral groove of .rod 18,

supported` a;

will thus be seen that rotation of rod, 18 will ause plate to move longitudinally of the oor A Ratchet wheels 24 and 25 are keyed to the forward end of rod 18, and sheave 26 is'jour-` naled'on the rod. Apawl 27,v secured to forward stud 19, engages ratchet wheel 24, and a pawl 28, secured to sheave 26, engages ratchet wheel 25. A coiled s ring 30 1s secured to a rod 31, projecting fir) urges sheave26 in the clockwisedirection, as seen in Fig. 1. f

The upper end of post 7 is threaded to receive a wheel 33. A1 scale 34, graduated in ,inches or calibrated tov read in pounds, eX-

tends upwardly adjacent the wheel 33, while an yarm extends from the post and is provided at its outer end with a collar 36 having a diametric pin 37 and adapted to-receive a vertical vrod 38 in sliding relation, pin 37 eX- tending through slot 40, in the rod. An arm 41 extends from rod 38 to engage theupper surface of wheel 33 thereby to support the rod in position.` An arm 42 is secured to rod 38 below slot 40 and a cable 43 depends from the outer end of arm 42 and is secured in the groove of sheave 26. Sleeve 10 has a lateral projection 44, bored at its outer end to receive the rod' 38 in sliding engagement, and adapted to Contact, in the upward movement of the cutter frame, with the collar of arm 42,.

f Thetensioning device ris, mounted on flange 13 and comprises a `threaded key 50 mounted in a stud 51, formed integral with flange 13. The threads of key V5() engage gear 52, having retained in yan inclined position to `facilitate its cutting action.

The opera-tion of my device yis as follows:

7 A `brick of cheese or other article to bey sliced is placedjon thefioor of the cutter with one end lying in the cutting plane and kone side om leg 3, and

` ashank 53 upon which wire 11 is wound, the

bearing against wall 14. Pin`22 is raised, and

plate 15 isV slid along the floor until it bears againstthe article. The pin is then released, and Wheel 21 rotated until the pin Afalls into engagement with thewspiral groove of'rod.r

18. The wheel 33 is adjusted until the desired thickness or Weight of slice is read on scale 34. v

The cutter frame is then raised, and :as Ait approaches the upward limit of its movement, extension 44 engages arm 42, thereby raising rod 38r and causing cable 43 to rotate sheave 26. Paw] 28 engages ratchet Wheel 25, thereby rotating rod 18, moving plate 15 toward the cutter frame and causing the article t0 be sliced to protrude beyond the cutting plane by the amount indicated on scale 34.

The upward movement or return stroke of the cutter is arrested by the upper surface of projection 42 contacting with the collar 86. The cutter frame is then depressed, causing wirell to sever a slice of the material. V'Rod 38 moves down with the cutter frame until its movement is arrested by the contact of arm 41 with wheel 33, While spring 30 which has ,been flexed by the up stroke rotates sheave 26, winding cable 43 upon the sheave. The clockwise rotation of the sheave upon rod 18 tends to turn the rod With it, and the purpose of ratchet wheel 24 and `pawl 27 is to prevent such rotation ofthe rod.

It willy be seen that the feeding operation is entirel automatic, since the reciprocation of han e 8 actuates both the cutting and feeding mechanism. v

I Wish it to be understood that various changesin the parts, and in their combination and arrangement may be made, suchchanges to be limitedl only by the scope of the subjeinedelaims. j

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
